Some of these data are collected in conjunction with the Environment Agency as part of their Water Framework Directive monitoring programme so other data from these locations or the surrounding area may be available upon request from the EA.

Sampling is carried out every three years on in a rolling cycle. Previous projects that this work builds on was carried out by CCW in Tremadog Bay and archived at CCW as Project 143 (Media 469). Data captured: Abundance (and in some cases biomass) of benthic invertebrates (per 0.1m2) and granulometry. Supporting determinants are: National Grid References, depth of sample relative to chart datum, salinity (if survey is in an estuary), sample depth (in grab). Digital images are also taken of each sample both in the grab and after sieving and these form part of the audit trail for each sample. All samples are collected using either a Day grab or a Long arm Van Veen grab (both 0.1m2). Benthic invertebrate samples are sieved over a 0.5mm mesh, some samples have been split into separate 0.5mm and 1mm fractions in order to maintain comparability with historic data sets.
